Background: The availability of two genetically very similar cell lines (A and B) derived from the laboratory isolate Entamoeba histolytica HM-1:IMSS, which differ in their virulence properties, provides a powerful tool for identifying pathogenicity factors of the causative agent of human...

Presents a study that investigated cases of suspected foci of amebiasis between October 1971 and June 1974 from the records of the Parasitic Diseases Branch of the Center for Disease Control of the U.S. Overdiagnosis of amebiasis; False reporting of leukocytes in stools as Entamoeba histolytica;...

Describes an outbreak of amebiasis in a family in the Netherlands, demonstrating that even with Western standards of hygiene, persistent cyst passage may result in the transmission of Entamoeba histolytica to household contacts. Use of molecular tools for the diagnosis and subsequent management...

The association of antibody responses with both innate and acquired immunity to amebiasis indicate that CD4+ T cells play a role in protection against Entamoeba histolytica infection. To test this hypothesis, we compared the genotype frequencies of human leukocyte antigen (HLA) class II alleles...

Entamoeba histolytica infection and colitis occurred in 55% and 4%, respectively, of a cohort of Bangladeshi preschool children observed for 2 years. DNA typing demonstrated that infecting E. histolytica isolates were genetically diverse. Innate resistance to infection in children was linked to...

Entamoeba histolytica is the causative agent of amoebiasis, a disease that produces dysentery as a result of the perforation of the large intestine. This parasite often invades other organs, primarily the liver, leading to an amoebic liver abscess (ALA), which can cause death. Metronidazole is...

Background: Human amoebiasis is caused by the parasitic protozoan Entamoeba histolytica that lives in the large intestine of hosts, where can produce asymptomatic colonization until severe invasive infections with blood diarrhea and spreading to other organs. The amoebic abscesses in liver are...
